Feel free to use them! The 1 with a spur on top is used to prevent confusion. In PE digits, it's used to prevent confusion with rotated versions of it (↾, ⇂ and ⇃). When using letter digits, you should use the 1 with a spur on top to prevent confusion with lowercase l. I need someone to remix this project, to put lowercase letters into this project.
